This is a LTS update, or Long Term Support. This means that this version will be supported for 3 years on Desktop version, and it is launched every two years (while normal releases are supported for 18 months and are launched every 6 months). Thousands of updates are coming daily for those who are using Beta 2 at this moment, so this is an evidence that the community is seriously working for 10.04 LTS.
This is a list of the most important updates that Ubuntu 10.04 has so far and what is supposed to come in the final release:
- Much better hardware support
- Improved speed
- 2 new default themes
- By default, Ubuntu has windows buttons on the left
- Splash and login screens are now modified
- Gwibber is installed by default (social client - Twitter is included)
- Boot time under 10 seconds (for the final release)
Ubuntu is still under full development, so the many applications and even the system can get serious errors, so if you need a stable system it is not recommended to update yet.
The stable version (9.10) and 10.04 beta 2 are both available from the official site: http://www.ubuntu.com/ .
